Claims. (Cl. 257-195) This invention relates to a cooler for uids. It is well adapted for the cooling of beer, etc.

Beer coolers now in use comprise pipe coils placed in ice water, ice boxes, etc. Cleaning of 5 the coils after they have become contaminated is an extremely diicult operation, and the task of removing the coils from the box or tank is so onerous that many bartenders allow the coils v to go for considerable lengths of time without cleaning. It is found that the contaminated coils destroy the flavor of the new beer and give it a at taste. When the pipe coils are cleaned, the beer in the coils is allowed to go to waste, and this loss during the period of the year becomes considerable.

The purpose of thepresent invention is to overcome the above mentioned disadvantages by providing cooling apparatus in which closed coils are dispensed with, and in which the parts may 2o be readily separated and cleaned. A further object is to provide apparatus in which beer or other uids may be quickly cooled to the desired temperature and maintained at that temperature. A further object is to provide separable cooler parts which may be removed for cleaning with a minimum of effort, and a construction in which the chill of the cooling medium is transmitted readily and over wide surfaces to the owing stream of beer. A further object is to provide improved valve or faucet mechanism having its operating parts removable for quick cleaning. Other specic objects and advantages will appear as the specification proceeds.

The invention is illustrated, in its preferred embodiments, by the accompanying drawings, in

which- Fig. l is a broken view in elevation of a cooler embodying my invention; Fig. 2, a broken top plan view; Fig. 3, a transverse sectional View,

the section being taken as indicated at line 3 of Fig. 1; Fig. 4, a longitudinal sectional view of a modied form of cooler embodying my invention, the section being taken as indicated at line 4 of Fig. 5; Fig. 5, a front end view of the cooler shown in Fig. 4; Fig. 6, an enlarged detail sectional view, the section being taken on line 4 of Fig. 5; Fig. 7, a broken longitudinal sectional view of a modied form of cooler embodying my invention, the section being taken as indicated at line 1 of Fig. 8. Figure 8 is a sectional view taken on the line 8 of Figure 7.

In the illustration given in Figs. 1 to 3, inclusive, A designates a cooling box or vat which may contain a cooling fluid; and B designates a cooler supported within box A,

The cooler B is provided with an outer cylindrical Wall I0 secured at its bottom to bottom cap II by solder or other suitable means. At its top, the cylinder IIl is secured to collar I2. The collar I2 is provided with diametrically op- 5 posed locking lugs I3 and I4. Below the lug I3 is a boss extension I5 which is-provided with an outlet opening I6 adapted to receive the outlet pipe I1.

Within the outer cylinder I0 is positioned an 10 inner tube or cylinder I8. The cylinder I8 is provided on its outer wall with inclined ribs I9 which bridge the space between cylinders I0 and I8, and form a helical channel 20 through which the beer may pass in its travel between 15 the two cylinders. Secured to the bottom of cylinder I8 is a bottom disk 2|. At the top of cylinder I8 is a collar 22 having an outwardly and downwardly extending flange 23. The flange 23 extends about collar I2 and forms a tight seal 20 therewith. If desired, a gasket 24 may be placed between the collar I2 and flange 23. The collar 22 is also provided with a centrally disposed bridge member 25 having a depression 26 in the center of its top surface and adapted to re- 25 ceive the end of locking screw 21.

A locking bar 2B having arms engaging lugs I3 and I4 of collar I2, is provided centrally with a nut 29 threadedly receiving the locking screw 21.

The inlet pipe 30 from the beer supply is illus- 30 trated as threadedly secured to the bottom disk I I and extends through suitable fitting and packing members in the bottom of box A.

It will be understood that the outlet pipe I1 is connected to a suitable valve or faucet from which 35 beer may be drawn. For example, a faucet of the type shown in Fig. 4 may be employed. The pipe I1, as is shown in Fig. 1, communicates with the top round of the helical passage 20.

In the operation of the cooler, a cooling iluid, 40 f such as ice water may be placed in box A and, if desired, within the inner container I8. The beer, or other fluid, travels from a source of supply through pipe 30 into the space between the cylinders I0 and I8 and passes upwardly until it 45 communicates with outlet pipe I1, where it is drawn 01T through the faucet. In cleaning the cooler, it is only necessary to release the locking screw 21, swing the locking bars 28 out of engagement with lugs I3 and I4, and then lift the 50 entire inner cylinder I8 out of container I0. This leaves an open cylinder I0 which may be cleaned in a very few moments. The removed mechanism exposes the space between ribs I9 for the direct application of a cleansing liquid, 55

and all foreign material can be readily removed. In replacing the inner cylinder I8, the reverse of the process described is followed.

In the construction shown in Figs. 4, 5 and 8, C represents an insulation box; D, refrigerant coils; and E, the inner cooler mechanism.

The box C may be of any suitable material adapted to enclose insulation about the coils D and cooler E. It consists of a casing 3l having an open top closed by head 32. Head 32 is equipped on its inner side with a raised collar 33.

The refrigerant coils D comprise a series of coils wound about the cooler E and leading to a source of refrigerant supply. The cooling medium may :be supplied by mechanical refrigeration, gas, etc. To conserve the cold supplied by coils D, any suitable amount of insulation may be packed around the coils and within the horizontal casing C.

The cooler E is in principle the same as the cooler shown in Fig. 1. .It is mounted, however, in horizontal position, and the beer inlet pipe 34 extends vertically through wall 3| and into the bottom portion of the cooler E. The cooler consists of an outer wall I0' and an inner wall I8', the inner wall being provided with inclined ribs I9' forming helical channels 20. 'Ihe bottom of cylinder I0 is closed by header I I'. A common header 35 closes both the inner cylinder I8 and the outer cylinder I8, a gasket 36 being preferably disposed between the top of cylinder I6', collar 33 and the head 35'. Head 35 also provides at its top a chamber or passage 31 which communicates with the helical passage 20'.

Threadedly connected to head 35 and communicating with passage or chamber 31 is a faucet F. The faucet consists of a hollow body member 38 having a threaded base 39 engaging a portion of head 35 and communicating with -'chamber 31. The outer portion of the body member 38 is provided with an` enlarged recess 49 adapted to receive an enlarged portion 4I of the valve casing 42. A threaded cap 38a locks the enlarged portion 4I within the body 38. The enlarged valve portion 4I is provided on its interior with a valve seat 43 communicating with a longitudinal passage 44 through the casing 42. A spout 45 is provided with a passage 46 communicating substantially at right angles with flow passage 44. A valve stern 41 extends through a bearing Wall 48 in the front portion of casing 42, and at its rear side, is provided with a valve body 48 shaped to conform with valve seat 43. The stem 41 extends rearwardly of the valve body 48 and carries a spider guide 49. The member 49 is provided with arms which engage the inner wall of member 4D and serve to maintain the stem centrally within the chamber. An extension 58 of stem 41 serves as an anchor for coil spring 5I. The inner free end of spring 5I is received within a slight recess 52 in the head 35.

The faucet casing 42 is provided with a weighted handle 53 pivotally secured to the end of the casing and provided with a downwardly curved lug 54 adapted to engage the projecting free end of Valve stem 41.

Thehead 35 may be releasably locked in position in any suitable manner. In the illustration given, the head is provided with a U-shaped recess 55, open at its top to receive a locking bar 56. The lockingbar is pivoted to the head 32 of casing C at 51. At its other end, the bar is provided with bifurcations 58 which engage a stud 59 carried by head 32. The stud 52 is threaded at its upper end and adapted to be en.- gaged by a lock nut 60.

In the operation of the modification shown in Figs. 4 and 5, beer passes through inlet tube 34 into the helical passage 20 between the cylinders I 0 and I 8 until it reaches chamber 31. From'- chamber 31, the beer is drawn off through faucet'- F. The refrigerating coils D maintain the cooler E at a temperature so that the beer in passing through the helical coils is quickly cooled to and maintained at the desired temperature. When it is desired to clean the mechanism, the locking bar 56 may be released from stud 59 by unscrewing nut 60 and swung back. The inner cylinder I0' together with head 35 may then be removed and readily cleaned. Faucet F may be cleaned at the same time by unscrewing the cap 38a and withdrawing the casing 42. If desired, the body casing 38 may also be removed by unscrewing it from its connection with head 35.

In the operation of the faucet F, 'the weighted handle 53 is drawn forward so as to bring lug 541 into contact with stem 41. The valve 48 is forced away from Valve seat 43, thus providing a ow passage through which beer may pass from chamber 31 into flow passage 44 and out through spout 45.

In the modification illustrated in Figs. '1 and 8, the outer cylinder 6I is substantially the same as outer casing III and IIJ heretofore described. The cylinder is secured at one end to a head 62 equipped with a hollow boss 63 receiving the beer inlet pipe 64. At its other end, the cylinder is embraced by a collar 65 carried by the casing G (shown only in part). A closure 66 is provided with a recessed flange 61 receiving both the collar 65 and the top portion of cylinder 6I. If desired, a sealing gasket 68 may be employed. The closure 66 is provided with a hollow boss 69 receiving an outlet pipe 10 leading to a faucet, preferably of the type described in connection with Fig. 4. Secured to casing G is a boss 1I to which is pivotally secured a locking bar 12. The locking bar 12 passes through a U-shaped recess 13 formed integral with closure 66 and is secured thereto by pin 14. YThe free end of bar 12 is recessed at 15 to receive locking stud 16 which is secured to boss 11 of casing G. The upper end of threaded stud 16 is engaged by nut 18, by which the bar 12 is releasably confined to stud 16.

The inner cylinder 19 is provided with a number of integral ribs 80 which are inclined so as to form a helical passage 8| between walls 6I and 19. The ribs or worms 89 may be formed by spinning or rolling the wall 16 into the shape illustrated. A bottom wall 82 is secured to the lower portion of cylinder 19. The other end of cylinder 19 is provided with a closure 82 which, in turn, is provided centrally with a handle 84.

In the operation of the apparatus, beer, or other fiuid, ilows through inlet pipe 64 from a source of supply, into the helical flow passage 8l to the top of the cooler, where it may be withdrawn through outlet pipe 10. It will be noted that handle 84 extends above cylinder 1I, and spaces closure 83 from the closure 66, thus providing a chamber 84a. With this modification, the closure 66 may be opened and closed without moving the inner cylinder 19. When it is desired to clean cylinder 19, the closure 66 may be i'irst opened and then the inner cylinder 19 lifted out by means of handle 84. The rolled ribs 89 not only make for a cheaper and sturdier construction, but also facilitate the cleaning operation, the rounded corners permitting the cleansing apparatus to readily remove all foreign materials.

While in the foregoing description, I have specied certain arrangements with cooling liquids and with refrigerants, it will be obvious that other arrangements may readily be made by a mechanic skilled in the art. The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.
